Numerous studies have led geneticists to conclude that all humans originated in Africa from as far back as 200,000 years ago.
However, human origins expert Chris Stringer,who works at the Natural History Museum in London, expressed skepticism regarding the use of modern genetic distributions alone, in determining where ancient people originated and lived in Africa hundreds of thousands years ago.

First off, Mr. Stringer, a British physical anthropologist well known for his studies on human evolution told Live Science, caution should be applied when using modern genetics as basis for inferences, especially in a large continent like Africa.
After all, there have been similar studies that traced earliest humans in different areas of the continent: Souther, Easter and Western Africa. The British anthropologist remarked that
“.. “So many studies have concentrated on one small bit of the genome, some others on one region; some focused on stone tool industry or on a single ‘critical’ fossil. Similarly in studies of genetics distribution, focusing on one area of cannot capture the full complexity surrounding our mosaic origins”
Arguments against Genetics Distribution as Determinant of Where Humans Originated
Stringer explained that the present study presented by geneticists follow only one series of maternally inherited genetic code. Yet such findings do not fully capture the full picture of how the earliest humankind traveled throughout Africa.
The best available findings is one that suggests there have been numerous and genetically-different founder populations that may have existed in different regions across the African continent. Evidence collected from such studies will then show proof that modern humans could have originated from several homelands rather than from just one.
